Trait for key expression format implementations.

This trait abstracts the differences between key expression formats used by different Zenoh-ROS bridges.

Required Associated Constants

const ESCAPE_CHAR: char

Escape character used to replace slashes in key expressions.

const ADMIN_SPACE: &'static str

Admin space prefix for liveliness tokens.

Required Methods

fn topic_key_expr(entity: &EndpointEntity) -> Result<TopicKE>

Generate topic key expression for data publication/subscription.

fn liveliness_key_expr( entity: &EndpointEntity, zid: &ZenohId, ) -> Result<LivelinessKE>

Generate liveliness token for endpoint entity discovery.

fn node_liveliness_key_expr(entity: &NodeEntity) -> Result<LivelinessKE>

Generate liveliness token for node entity discovery.

fn parse_liveliness(ke: &KeyExpr<'_>) -> Result<Entity>

Parse liveliness token back to entity.

fn encode_qos(qos: &QosProfile, keyless: bool) -> String

Encode QoS for liveliness token.

fn decode_qos(s: &str) -> Result<(bool, QosProfile)>

Decode QoS from liveliness token.

Provided Methods

fn mangle_name(name: &str) -> String

Mangle a name (replace slashes with escape char).

fn demangle_name(name: &str) -> String

Demangle a name (restore slashes from escape char).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
